Description

Method, device and system for managing wireless resources

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a system for managing wireless resources.

Background

Based on Carrier Aggregation (CA) technology, a Cell (Cell) served by a base station for a UE is divided into a Primary Cell (Primary Cell, PCell for short) and a Secondary Cell (Secondary Cell, SCell for short). The primary cell is a cell for establishing Radio Resource Control (RRC for short) in a serving cell of the UE, and the secondary cell is a cell other than the primary cell in the serving cell of the UE.

Long Term Evolution (LTE) provides an Activation/Deactivation (Activation/Deactivation) mechanism for a secondary cell. When one secondary cell is activated, the UE may perform data transmission and reception on the secondary cell; when one secondary cell is deactivated, the UE does not perform data transmission and reception on the secondary cell.

When a secondary cell is activated, the state of the secondary cell is an open state, and a base station to which the secondary cell belongs needs to transmit some other signals besides receiving data transmitted by the UE and transmitting data required by the UE, which sometimes causes unnecessary power overhead and interference.

Example 7

Referring to fig. 11, the system according to an embodiment of the present invention includes an apparatus 701 for managing radio resources provided in one embodiment or the second embodiment and an apparatus 702 for managing radio resources provided in the third embodiment or the fourth embodiment.

First, an application scenario of the method for managing radio resources provided by the present invention is briefly described with reference to fig. 12 and 13.

In CA technology, a UE may communicate on multiple carriers simultaneously, including a primary carrier and a secondary carrier. The cell working on the main carrier is a main cell, and the cell working on the auxiliary carrier is an auxiliary cell. The base stations of the primary cell and the secondary cell may be the same base station or different base stations.

For example, referring to fig. 12, UE 1 communicates with the first base station 2 on a primary carrier (e.g., 800MHz), the serving cell of the first base station 2 is a primary cell, and the primary cell is kept in an open state all the time. The UE 1 and the second base station 3 communicate on a secondary carrier (e.g. 900MHz), a serving cell of the second base station 3 is a secondary cell, and according to the network data amount and the interference condition, a base station to which the secondary cell belongs may open or close a carrier in which the secondary cell is located, for example, there is data transmission in the secondary cell, or when the channel of the primary cell is congested due to an increase in the amount of transmitted data, the base station to which the secondary cell belongs may open the carrier in which the secondary cell is located, for example, there is no data transmission in the secondary cell, or the amount of transmitted data is small and the primary cell is sufficient to cope, or when the interference level in the network is high, the base station to which the secondary cell belongs may close the carrier in which the secondary cell is located.

For another example, referring to fig. 13, the UE 1 and the second base station 3 perform data transmission on the primary carrier and the secondary carrier simultaneously. In the serving cells of the second base station 3, a cell operating on the primary carrier is a primary cell, and a cell operating on the secondary carrier is a secondary cell. Similarly, the base station to which the secondary cell belongs may turn on or off the carrier in which the secondary cell is located according to the network data amount and the interference situation.

The first base station 2 and the second base station 3 may be both macro base stations, micro base stations, macro base stations and micro base stations, and the comparison of the present invention is not limited. The macro base station is a base station with large transmitting power and high erection height. The macro base station has a wide coverage area, the number of UEs served by each macro base station is generally large, and the data transmission rate between each UE and the macro base station is low. The micro base station is a base station with low transmitting power and low erection height (generally installed on a utility facility such as a telegraph pole). The micro base stations can be densely deployed, the number of the UE served by each micro base station is small, and the data transmission rate between each UE and the micro base station is high.

When the base stations of the main cell and the auxiliary cell are different base stations, the base station of the main cell and the base station of the auxiliary cell are connected by a backhaul link, and the backhaul link can be optical fiber, cable or microwave transmission. The base station to which the main cell belongs and the base station to which the auxiliary cell belongs carry out rapid communication through a backhaul link, so that the base station to which the main cell belongs can assist the base station to which the auxiliary cell belongs to carry out communication with the UE.

The application scenarios of the method for managing radio resources described above are merely examples, and the present invention is not limited thereto.

Example 8

An embodiment of the present invention provides a method for managing radio resources, where the method may be performed by a base station, and referring to fig. 14, the method includes:

step 801: the serving base station of the UE determines that the state of the secondary cell of the UE needs to be changed to an uplink on and downlink off state.

Step 802: and the service base station of the UE changes the state of the auxiliary cell, so that the state of the auxiliary cell is an uplink open state and a downlink closed state.

In this embodiment, the uplink is a direction from the UE to the serving base station of the UE, and the downlink is a direction from the serving base station of the UE to the UE. When the state of the secondary cell is an uplink on state and a downlink off state, the uplink signal sent by the UE to the base station to which the secondary cell belongs through the secondary cell can be received by the base station to which the secondary cell belongs, and the downlink signal sent by the base station to the UE through the secondary cell can only be sent in the subframe for sending the DRS. The uplink signal includes at least one of an uplink reference signal, an uplink control signaling, and uplink data. The downlink signal includes at least one of a downlink reference signal, a downlink control signaling, and downlink data.

In a specific implementation, when the CA technology is used, the UE first accesses the primary cell, and the base station to which the primary cell belongs configures the secondary cell for the UE by sending configuration information to the UE, so that the UE knows that the secondary cell can be used for communication. Further, after the UE receives the activation signaling of the secondary cell sent by the base station to which the primary cell belongs, and the UE activates the secondary cell according to the activation signaling of the secondary cell, the UE uses the secondary cell for communication, which is the prior art and will not be described in detail herein. The base station to which the primary cell belongs may be the same as the base station to which the secondary cell belongs (as in the scenario shown in fig. 13), or may be different from the base station to which the secondary cell belongs (as in the scenario shown in fig. 12).

The serving base station of the UE may also change the state of the secondary cell, so that the state of the secondary cell is an uplink open state and a downlink open state. When the state of the auxiliary cell is the uplink open state and the downlink open state, the uplink signal sent by the UE to the base station to which the auxiliary cell belongs through the auxiliary cell can be received by the base station to which the auxiliary cell belongs, and the downlink signal sent by the base station to the UE through the auxiliary cell can be sent.

The serving base station of the UE may also change the state of the secondary cell, so that the state of the secondary cell is an uplink closed state and a downlink open state. When the state of the auxiliary cell is an uplink closed state and a downlink open state, the uplink signal sent by the UE to the base station to which the auxiliary cell belongs through the auxiliary cell cannot be received by the base station to which the auxiliary cell belongs, and the downlink signal sent by the base station to the UE through the auxiliary cell can be sent.

The serving base station of the UE may also change the state of the secondary cell, so that the state of the secondary cell is an uplink closed state and a downlink closed state. When the state of the secondary cell is an uplink closed state and a downlink closed state, the uplink signal sent by the UE to the base station to which the secondary cell belongs through the secondary cell cannot be received by the base station to which the secondary cell belongs, and the downlink signal sent by the base station to the UE through the secondary cell can only be sent in the subframe where the DRS is sent.

Example 9

The embodiment of the invention provides a method for managing wireless resources, which can be executed by UE and can be realized by adopting the following three modes:

the first method comprises

steps

901 and 902, as shown in fig. 15, and the specific steps are as follows:

step 901: when the UE works in the uplink activation and downlink activation state of the auxiliary cell, the UE receives an uplink activation signaling sent by a service base station of the UE.

Step 902: and the UE performs uplink activation on the auxiliary cell of the UE according to the uplink activation signaling, so that the UE works in an uplink activation and downlink deactivation state of the auxiliary cell.

The second way comprises steps 903-904, see fig. 16, which includes the following steps:

step 903: when the UE works in the uplink activation and downlink activation state of the auxiliary cell, the UE receives a downlink deactivation signaling of the UE sent by a service base station of the UE.

Step 904: and the UE carries out downlink deactivation of the auxiliary cell according to the downlink deactivation signaling, so that the UE works in an uplink activation and downlink deactivation state of the auxiliary cell.

The third method includes step 905, see fig. 17, which includes the following specific steps:

step 905: when the UE works in the uplink activation and downlink activation state of the auxiliary cell, if the UE receives the uplink scheduling signaling of the auxiliary cell within the set time and does not receive the downlink scheduling signaling of the auxiliary cell, the UE performs downlink deactivation of the auxiliary cell, so that the UE works in the uplink activation and downlink deactivation state of the auxiliary cell.

In this embodiment, the uplink scheduling signaling of the secondary cell is used to schedule transmission of uplink data in the secondary cell, and the downlink scheduling signaling of the secondary cell is used to schedule reception of downlink data in the secondary cell. When the UE works in the uplink activation and downlink deactivation state of the auxiliary cell, the uplink signal sent by the UE to the base station to which the auxiliary cell belongs through the auxiliary cell can be sent, the downlink signal sent by the base station to the UE through the auxiliary cell can only be received by the UE in the subframe for sending the DRS, the uplink signal comprises at least one of an uplink reference signal, an uplink control signaling and uplink data, and the downlink signal comprises at least one of a downlink reference signal, a downlink control signaling and downlink data.

The UE may also operate in an uplink active and downlink active state in the secondary cell. When the UE works in the uplink activation and downlink activation state of the auxiliary cell, the uplink signal sent by the UE to the base station to which the auxiliary cell belongs through the auxiliary cell can be sent, and the downlink signal sent by the base station to the UE through the auxiliary cell to which the auxiliary cell belongs can be received by the UE.

The UE may also operate in an uplink deactivated and downlink activated state in the secondary cell. When the UE works in the uplink deactivation and downlink activation state of the auxiliary cell, the uplink signal sent by the UE to the base station to which the auxiliary cell belongs through the auxiliary cell cannot be sent, and the downlink signal sent by the base station to the UE through the auxiliary cell to which the auxiliary cell belongs can be received by the UE.

The UE may also operate in an uplink deactivated and downlink deactivated state in the secondary cell. When the UE works in the uplink deactivation and downlink deactivation state of the auxiliary cell, the uplink signal sent by the UE to the base station to which the auxiliary cell belongs through the auxiliary cell cannot be sent, and the downlink signal sent by the base station to the UE through the auxiliary cell can only be received by the UE in the subframe for sending the DRS.

Example 10

In this embodiment, the initial state of the secondary cell is an uplink off state and a downlink off state, that is, an uplink signal cannot be received in the secondary cell by a base station to which the secondary cell belongs, and a downlink signal can be transmitted in the secondary cell by the base station to which the secondary cell belongs only in a subframe where a DRS is transmitted, referring to fig. 18, the method includes:

step 1001: and the serving base station of the UE sends the configuration information of the secondary cell to the UE.

When the CA technology is adopted, the UE firstly accesses the main cell, the base station to which the main cell belongs configures the auxiliary cell for the UE by sending the configuration information to the UE, so that the UE can know that the auxiliary cell can be used for communication. Further, after the UE receives the activation signaling of the secondary cell sent by the base station to which the primary cell belongs, and the UE activates the secondary cell according to the activation signaling of the secondary cell, the UE uses the secondary cell for communication, which is the prior art and will not be described in detail herein. The base station to which the primary cell belongs may be the same as the base station to which the secondary cell belongs (as in the scenario shown in fig. 13), or may be different from the base station to which the secondary cell belongs (as in the scenario shown in fig. 12).

In this step 1001, the serving base station of the UE is the base station to which the primary cell belongs.

Step 1002: the serving base station of the UE determines that the state of the secondary cell of the UE needs to be changed to an uplink on and downlink off state.

In an implementation manner of this embodiment, the step 1002 may include:

a service base station of the UE acquires the current state of the auxiliary cell;

a service base station of the UE acquires a network state of a service cell of the UE, wherein the service cell comprises a main cell and an auxiliary cell of the UE;

and the service base station of the UE determines that the state of the auxiliary cell needs to be changed into an uplink open state and a downlink closed state according to the current state of the auxiliary cell and the network state of the service cell.

The uplink is a direction from the UE to the serving base station of the UE, and the downlink is a direction from the serving base station of the UE to the UE.

In a specific implementation, a serving base station of the UE may determine whether uplink data is currently to be transmitted in the secondary cell by whether receiving an uplink scheduling request sent by the UE, determine whether downlink data is currently to be transmitted in the secondary cell by using a data cache state of a base station to which the secondary cell belongs, determine an uplink data amount to be transmitted in the primary cell by using a data cache state reported by the UE, determine a downlink data amount to be transmitted in the primary cell by using a data cache state of a base station to which the primary cell belongs, determine uplink interference values to be transmitted in the primary cell and the secondary cell by using an interference condition reported after measurement by the UE, and determine downlink interference values to be transmitted in the primary cell and the secondary cell by directly measuring and receiving measurement results of other base stations.

For example, when determining whether there is uplink data to be transmitted in the secondary cell, when the UE needs to send the uplink data, the UE may send an uplink scheduling request to a serving base station of the UE (which may be a base station to which the primary cell belongs or a base station to which the secondary cell belongs), and meanwhile, since the base stations are connected by using a backhaul link, fast interworking of messages may be performed, so whether the serving base station of the UE and the base station to which the secondary cell belongs are the same base station or not, the serving base station of the UE may determine whether there is uplink data to be transmitted in the secondary cell according to whether the uplink scheduling request sent by the UE is received or not.

For another example, when the base station to which the primary cell belongs and the base station to which the secondary cell belongs are different base stations, if the serving base station of the UE is the base station to which the primary cell belongs, the serving base station of the UE may obtain the data cache state of the base station to which the secondary cell belongs through the backhaul link, and further determine whether downlink data to be transmitted in the secondary cell currently exists; if the serving base station of the UE is the base station to which the secondary cell belongs, the serving base station of the UE may obtain the data cache state of the base station to which the primary cell belongs through the backhaul link, and further determine the amount of downlink data to be currently transmitted in the primary cell.

For another example, when determining the uplink interference value currently transmitted in the secondary cell, the UE measures the receiving powers of the downlink reference signals received in the primary cell and the secondary cell, respectively, and obtains the transmitting power of the downlink reference signal from the downlink reference signal, and determines the uplink interference values currently transmitted in the primary cell and the secondary cell to be reported to the serving base station of the UE by calculating the difference between the receiving power of the downlink reference signal and the transmitting power of the downlink reference signal, so that the serving base station of the UE further determines the uplink interference values currently transmitted in the primary cell and the secondary cell.

Similarly, when determining the downlink interference value currently transmitted in the secondary cell, the serving base station of the UE measures the received power of the uplink reference signal transmitted by the UE, and obtains the transmitted power of the uplink reference signal from the uplink reference signal, and obtains the measurement result of the base station to which the primary cell belongs and/or the base station to which the secondary cell belongs through the backhaul link by calculating the difference between the received power of the uplink reference signal and the transmitted power of the uplink reference signal, and when the serving base station of the UE is not the base station to which the primary cell belongs and/or the base station to which the secondary cell belongs, determines the downlink interference value currently transmitted in the primary cell and the secondary cell.

It can be understood that, in step 1002, the serving base station of the UE may be a base station to which the primary cell belongs, and may also be a base station to which the secondary cell belongs.

Optionally, the determining, by the serving base station of the UE, that the state of the secondary cell needs to be changed to the uplink on and downlink off states according to the current state of the secondary cell and the network state of the serving cell may include:

When the state of the secondary cell is an uplink on state and a downlink off state, the uplink signal sent by the UE to the base station to which the secondary cell belongs through the secondary cell can be received by the base station to which the secondary cell belongs, and the downlink signal sent by the base station to the UE through the secondary cell can only be sent in the subframe where the DRS is sent. The uplink signal includes at least one of an uplink reference signal, an uplink control signaling, and uplink data. The downlink signal includes at least one of a downlink reference signal, a downlink control signaling, and downlink data.

The uplink reference signal is used to detect the channel quality of the uplink portion, the uplink control signaling is signaling for controlling data transmission sent by the UE to the base station to which the secondary cell belongs, and the uplink data is data sent by the UE to the base station to which the secondary cell belongs, such as a photo uploaded by a user to the network. The downlink reference signal is used to detect the channel quality of the downlink portion, the downlink control signaling is a signaling sent by the base station to which the secondary cell belongs to the UE for controlling data transmission, and the downlink data is data sent by the base station to which the secondary cell belongs to the UE, such as a webpage browsed by a user.

Specifically, when the state of the secondary cell is the uplink off state and the downlink off state, if the serving base station of the UE and the base station to which the secondary cell belongs are the same base station, step 1003a is executed; if the serving base station of the UE is different from the base station to which the secondary cell belongs, step 1003b is executed.

Step 1003 a: and the service base station of the UE switches the state of the auxiliary cell into an uplink open state and a downlink closed state.

In a specific implementation, a register (buffer) for setting the state of the secondary cell is provided in the base station to which the secondary cell belongs, and a value in the register indicates the state of the secondary cell, and if the value in the register is 01, the state of the secondary cell is an uplink on state and a downlink off state. Because the serving base station of the UE and the base station to which the auxiliary cell belongs are the same base station, the serving base station of the UE can directly change the value in the register, thereby changing the state of the auxiliary cell into an uplink open state and a downlink closed state.

In this step 1003a, when the serving base station of the UE and the base station to which the secondary cell belongs are the same base station, the serving base station of the UE may be the base station to which the primary cell belongs or may not be the base station to which the primary cell belongs. When the serving base station of the UE is the base station to which the master cell belongs, the base station to which the master cell belongs and the base station to which the slave cell belongs are the same base station, and when the serving base station of the UE is not the base station to which the master cell belongs, the base station to which the master cell belongs and the base station to which the slave cell belongs are different base stations.

Step 1003 b: and the service base station of the UE sends a control instruction, wherein the control instruction is used for instructing the base station to which the auxiliary cell belongs to switch the state of the auxiliary cell into an uplink open state and a downlink closed state.

It can be understood that, in step 1003b, the serving base station of the UE may be a base station to which the primary cell belongs, or may be a base station to which a secondary cell other than the secondary cell in the handover state belongs in the serving cell of the UE.

It can be understood that, by executing step 1003a or 1003b, the serving base station may change the state of the secondary cell, so that the state of the secondary cell is an uplink on state and a downlink off state.

Step 1004: and the service base station of the UE sends an uplink activation signaling to the UE, wherein the uplink activation signaling is used for indicating the UE to carry out uplink activation of the auxiliary cell. This step 1004 is an optional step, and may be executed after step 1003a or after step 1003 b.

In a specific implementation, when the base station to which the primary cell belongs is the same as the base station to which the secondary cell belongs, after the state of the secondary cell is the uplink on and downlink off state (step 1003a), the base station to which the primary cell belongs (i.e., the base station to which the secondary cell belongs) may directly send the uplink activation signaling of the secondary cell to the UE. When the base station to which the primary cell belongs is different from the base station to which the secondary cell belongs, after the state of the secondary cell is the uplink on and downlink off state (step 1003b), the base station to which the secondary cell belongs first sends the uplink activation signaling of the secondary cell to the base station to which the primary cell belongs through the backhaul link, and then the base station to which the primary cell belongs sends the uplink activation signaling of the secondary cell to the UE.

Step 1005: and when the UE works in the uplink deactivation and downlink deactivation state of the auxiliary cell, the UE activates the uplink of the auxiliary cell according to the uplink activation signaling, so that the UE enters the uplink activation and downlink deactivation state of the auxiliary cell.

It can be understood that, if the UE receives the uplink activation signaling and the downlink activation signaling, the UE may perform uplink activation and downlink activation of the secondary cell simultaneously, where the UE specifically has the following behaviors:

1) sending a Sounding Reference Signal (SRS) to a base station to which the secondary cell belongs, where the SRS is one of uplink Reference signals;

2) measuring the downlink channel quality of the auxiliary cell, and reporting the measurement result to the base station to which the auxiliary cell belongs;

3) detecting a Physical Downlink Control Channel (PDCCH for short) corresponding to the secondary cell, where the PDCCH is used to transmit a Downlink Control signaling, both an uplink scheduling (uplink grant) signaling and a Downlink scheduling signaling (Downlink assignment) are transmitted through the PDCCH, the uplink scheduling signaling and the Downlink scheduling signaling are both one of the Downlink Control signaling, the uplink scheduling signaling is used to schedule transmission of uplink data in the secondary cell, and the Downlink scheduling signaling is used to schedule transmission of Downlink data in the secondary cell;

4) a Deactivation clock (Secondary Cell Deactivation Timer) of the Secondary Cell is started or restarted.

Specifically, the serving base station of the UE configures the UE with the parameter information sent by the SRS. When the auxiliary cell of the UE is deactivated, the UE stops sending the SRS; and once the secondary cell is activated, resuming the sending of the SRS according to the SRS configuration parameter information before.

This is prior art and will not be described in detail herein.

Compared with the prior art that the uplink activation and the downlink activation of the secondary cell are simultaneously performed, after only the uplink activation of the secondary cell is performed, the UE cannot perform downlink channel quality measurement on the secondary cell, and cannot report a measurement result to a base station to which the secondary cell belongs. The measurement result includes a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), and a Precoding Type Indicator (PTI).

In an implementation manner of this embodiment, when the UE enters the uplink activated and downlink deactivated state of the secondary cell, the method may further include:

the UE starts an uplink deactivation clock of the auxiliary cell, and the value of the uplink deactivation clock of the auxiliary cell is a set first initial value when being started;

when the UE receives an uplink scheduling signaling of the auxiliary cell in a subframe for receiving downlink signals, the UE resets the value of an uplink deactivation clock of the auxiliary cell to a first initial value;

when the UE does not receive the uplink scheduling signaling of the auxiliary cell in the subframe receiving the downlink signal, the UE subtracts 1 from the value of the uplink deactivation clock of the auxiliary cell;

In practical application, two Secondary Cell Deactivation clocks (Secondary Cell Deactivation Timer) are set in the UE, which are a Secondary Cell uplink Deactivation clock (Secondary Cell Deactivation Timer _ uplink) and a Secondary Cell downlink Deactivation clock (Secondary Cell Deactivation Timer _ downlink), respectively. The uplink deactivation clock of the secondary cell and the downlink deactivation clock of the secondary cell may use the existing counter (i.e. the deactivation clock of the secondary cell), or introduce a new counter. The first initial value is preset by the network for the UE, for example, 640 subframes (subframes).

In other embodiments, the uplink activation and the downlink activation of the secondary cell may be performed simultaneously, when the UE performs the uplink activation and the downlink activation of the secondary cell simultaneously, the UE starts an uplink deactivation clock of the secondary cell and a downlink deactivation clock of the secondary cell simultaneously, a value of the uplink deactivation clock of the secondary cell is a set first initial value when the uplink deactivation clock of the secondary cell is started, and a value of the downlink deactivation clock of the secondary cell is a set second initial value when the downlink deactivation clock of the secondary cell is started; when the UE receives an uplink scheduling signaling of the auxiliary cell in a subframe for receiving downlink signals, the UE resets the value of an uplink deactivation clock of the auxiliary cell to a first initial value; when the UE does not receive the downlink scheduling signaling of the auxiliary cell in the subframe receiving the downlink signal, the UE subtracts 1 from the value of the downlink deactivation clock of the auxiliary cell; and when the value of the downlink deactivation clock of the auxiliary cell is reduced to 0, the UE performs downlink deactivation of the auxiliary cell, so that the UE enters an uplink activation and downlink deactivation state of the auxiliary cell.

Of course, when the UE receives the downlink scheduling signaling of the secondary cell in the subframe receiving the downlink signal, the UE also resets the value of the downlink deactivation clock of the secondary cell to the second initial value. When the UE does not receive the uplink scheduling signaling of the secondary cell in the subframe receiving the downlink signal, the UE may also subtract 1 from the value of the uplink deactivation clock of the secondary cell. And when the value of the uplink deactivation clock of the auxiliary cell is reduced to 0, the UE performs uplink deactivation of the auxiliary cell.

In another implementation manner of this embodiment, when the UE operates in an uplink activated and downlink deactivated state of the secondary cell (at this time, the state of the secondary cell is uplink on and downlink off), the method may further include:

a serving base station of the UE sends uplink scheduling signaling of an auxiliary cell to the UE on other cells except the auxiliary cell in a serving cell of the UE, wherein the serving cell comprises a main cell and the auxiliary cell;

alternatively, the first and second electrodes may be,

and the service base station of the UE sends the uplink scheduling signaling of the auxiliary cell to the UE in the subframe of the DRS sent by the auxiliary cell.

Specifically, in the serving cell of the UE, other cells except the secondary cell may be the primary cell, or may be other secondary cells except the secondary cell.

According to the existing LTE protocol, before the UE sends uplink data to the base station to which the secondary cell belongs, the base station to which the secondary cell belongs needs to send an uplink scheduling signaling to the UE, where the uplink scheduling signaling usually carries information of tens of bits (bit), so that the UE knows the time (time-frequency position for sending uplink data, e.g. after receiving the 4 th subframe after the uplink scheduling signaling, i.e. after 4 ms) for sending the uplink data, the format (modulation and coding mode of the uplink data, etc.) and so on, and controls and assists transmission of the uplink data. The UE receiving the uplink scheduling signaling means that the UE obtains the right to transmit uplink data.

In this embodiment, the uplink scheduling signaling is transmitted through a PDCCH corresponding to the secondary cell. In other embodiments, the uplink scheduling signaling may be transmitted through an Enhanced Physical Downlink Control Channel (EPDCCH) Channel in addition to the PDCCH Channel, which is the prior art and is not described in detail herein.

If the base station to which the primary cell belongs is different from the base station to which the secondary cell belongs, the serving base station of the UE sends the uplink scheduling signaling of the secondary cell to the UE in the serving cell of the UE on other cells except the secondary cell, which may include: the base station to which the auxiliary cell belongs sends the uplink scheduling signaling of the auxiliary cell to the base station to which the main cell belongs through a backhaul link; and the base station to which the main cell belongs sends the uplink scheduling signaling of the auxiliary cell to the UE.

Whether the base station to which the primary cell belongs is the same as the base station to which the secondary cell belongs, the uplink scheduling signaling of the secondary cell can be sent to the UE in the subframe in which the secondary cell sends the DRS. The DRS is a signal periodically transmitted by a base station to which the secondary cell belongs when the state of the secondary cell is a downlink off state (including an uplink off and downlink off state and an uplink on and downlink off state). The main purpose of transmitting DRS is to enable the UE to discover the presence of a secondary cell. Generally, a transmission period of the DRS may be set to be relatively long, for example, several tens or hundreds of milliseconds (ms) are transmitted once. The longer transmission period of the DRS can reduce the power consumption of the secondary cell and also reduce the interference of the secondary cell to surrounding cells.

It can be understood that, when the state of the secondary cell is the uplink open state and the downlink open state, the uplink scheduling signaling of the secondary cell is directly sent to the UE by the base station to which the secondary cell belongs.

In another implementation manner of this embodiment, when the UE operates in an uplink activated and downlink deactivated state of the secondary cell (at this time, the heating state of the secondary cell is an uplink on and downlink off state), the method may further include:

the method comprises the steps that a service base station of the UE sends feedback signaling to the UE on other cells except an auxiliary cell in a service cell of the UE;

alternatively, the first and second electrodes may be,

a service base station of the UE sends a feedback signaling to the UE in a subframe of a DRS sent by a secondary cell;

After receiving the uplink data, the base station to which the secondary cell belongs demodulates the data. If the uplink data is correctly received, an Acknowledgement (ACK) signaling is fed back to the user; if the uplink data reception fails, a Negative Acknowledgement (NACK) signaling is fed back to the user. The ACK signaling or NACK signaling may be sent to the UE after the UE sends uplink data, for example, 4ms later (subframe No. 8 after receiving uplink scheduling signaling). And when the state of the auxiliary cell is an uplink open state and a downlink open state, the ACK signaling or the NACK signaling is directly sent to the UE by the base station to which the auxiliary cell belongs. At this time, since the state of the secondary cell is the downlink off state, the ACK signaling or NACK signaling (generally referred to as feedback signaling, generally only 1-2 bits) may be sent to the UE by the serving base station of the UE in the above manner.

The ACK signaling or the NACK signaling may be transmitted through a Physical Hybrid automatic repeat-request Indicator Channel (PHICH) Channel, an Enhanced Physical Hybrid automatic repeat-request Indicator Channel (EPHICH) Channel, a PDCCH Channel, or an EPDCCH Channel. This is prior art and will not be described in detail herein.

In another implementation manner of this embodiment, the method may further include:

UE acquires the transmission power of DRS;

the method comprises the steps that UE receives a DRS sent by a service base station of the UE and measures the receiving power of the DRS;

the UE calculates the path loss of communication in the auxiliary cell according to the transmission power of the DRS and the receiving power of the DRS;

and the UE calculates the power of the UE for sending the uplink signal in the auxiliary cell according to the path loss of the communication in the auxiliary cell.

Specifically, the UE may obtain the transmission power of the DRS, receive a transmission power indication of the DRS transmitted by a serving base station of the UE, or directly obtain the transmission power of the CRS from a higher layer signaling when the transmission power of the DRS is the same as the transmission power of the CRS (which is a basis object of the conventional calculation method), and then calculate by using the transmission power of the CRS instead of the transmission power of the DRS.

In practical application, the transmission power of the DRS is the transmission power of the DRS on each Resource unit (Energy Per Resource Element, abbreviated as EPRE).

Optionally, the calculating, by the UE, a path loss for communicating in the secondary cell according to the transmission power of the DRS and the reception power of the DRS may include:

UE calculates the path loss PL of downlink signal transmission in the auxiliary cell according to the formula (1)_DL：

PL_DL＝RSTP_DRS-RSRP_DRS (1)；

Wherein, RSTP_DRSThe Transmission Power of DRS, i.e. Reference Signal Transmission Power (RSTP), RSRP_DRSThe received Power of DRS, i.e. the Reference Signal Receiving Power (RSRP).

Optionally, the calculating, by the UE, power of the UE for sending the uplink signal in the secondary cell according to the path loss for communication in the secondary cell may include:

UE calculates the transmission power P of PUCCH signal according to the formula (2)_PUCCH：

P_PUCCH＝min{P_max，P₀+PL_DL+△_Format+δ} (2)；

The UE calculates the transmit power P of a Physical Uplink Shared Channel (PUSCH) signal according to formula (3)_PUSCH：

P_PUSCH＝min{P_max，P₀+α*PL_DL+10*log₁₀(M)+△_MCS+δ} (3)；

UE calculates SRS transmission power P according to formula (4)_SRS：

P_SRS＝min{P_max，P₀+α*PL_DL+10*log₁₀(M_SRS)+δ+P_SRS0} (4)；

Wherein, min {₁，*₂Is taken₁、*₂Minimum value of (1), P_maxIs the maximum transmission of the UERadio power, P₀Is a target power value, PL, of a base station desired signal_DLΔ path loss for transmission of downlink data on secondary cell_FormatIs a value for compensating PUCCHs with different formats, delta is a closed loop power control compensation value, alpha is a path loss compensation coefficient, log₁₀Taking logarithm with base 10 as pair, M allocates bandwidth for PUSCH, and Delta_MCSCompensation values, M, for different Modulation and Coding Schemes (MCS)_SRSAllocating bandwidth, P, for SRS_SRS0Is a configurable power compensation value for SRS.

Since the path loss of the downlink signal is substantially the same as the path loss of the uplink signal, the UE generally calculates the transmission power of the uplink signal by directly replacing the measured path loss of the downlink signal with the measured path loss of the uplink signal. Compared with the path loss of the uplink signal detected by the serving base station for receiving the UE, the method is more convenient and quicker, and the transmitting power of the UE is more timely adjusted according to the change of the path loss of the uplink signal.

In the LTE system, uplink signals are classified into three types, which are PUCCH signals, PUSCH signals, and SRS signals, respectively. The PUCCH is used for transmitting ACK signaling or NACK signaling, CQI, PMI, RI, and other uplink control signaling. The PUSCH is used to transmit uplink data that the UE actually sends to the base station. The SRS is used for measurement of uplink channel quality. The power of any uplink signal is required to be according to PL_DLAnd (4) calculating.

P₀、△_Format、δ、α、M、△_MCS、M_SRS、P_SRS0The UE is informed by its serving base station. Relative to P₀、△_FormatThe serving base station of the UE may change δ frequently, so that the UE may adjust the transmit power up or down at any time to achieve fast control of the transmit power of the UE.

Step 1006: when the UE completes sending the uplink data, the serving base station of the UE changes the state of the secondary cell, so that the state of the secondary cell is an uplink closed state and a downlink closed state.

Specifically, this step 1006 may include:

if the serving base station of the UE and the base station to which the auxiliary cell belongs are the same base station, the serving base station of the UE switches the state of the auxiliary cell into an uplink closed state and a downlink closed state;

alternatively, the first and second electrodes may be,

and if the serving base station of the UE and the base station to which the auxiliary cell belongs are different base stations, the serving base station of the UE sends a control instruction, and the control instruction is used for instructing the base station to which the auxiliary cell belongs to switch the state of the auxiliary cell to an uplink closed state and a downlink closed state.

Step 1007: and the service base station of the UE sends an uplink deactivation signal to the UE, wherein the uplink deactivation signal is used for indicating the UE to carry out uplink deactivation of the auxiliary cell.

Step 1008: and the UE carries out uplink deactivation of the auxiliary cell according to the uplink deactivation signaling.

After uplink deactivation of the secondary cell is performed, the UE specifically has the following behaviors:

1) stopping sending the SRS to the base station to which the secondary cell belongs;

2) stopping measuring the downlink channel quality of the auxiliary cell and reporting the measurement result to the base station to which the auxiliary cell belongs;

3) the PDCCH corresponding to the auxiliary cell is not detected any more, and the uplink scheduling signaling is transmitted through the PDCCH;

4) uplink data is not transmitted on the secondary cell.

Example 11

In this embodiment, the initial state of the secondary cell is an uplink open state and a downlink open state, that is, an uplink signal can be received in the secondary cell by a base station to which the secondary cell belongs, and a downlink signal can be sent in the secondary cell by the base station to which the secondary cell belongs, referring to fig. 19, the method includes:

step 1101: the serving base station of the UE determines that the state of the secondary cell of the UE needs to be changed to an uplink on and downlink off state.

Specifically, the step 1101 may be the same as the step 1002, and will not be described in detail herein.

In this embodiment, when the state of the secondary cell is an uplink on state and a downlink off state, an uplink signal sent by the UE to the base station to which the secondary cell belongs through the secondary cell can be received by the base station to which the secondary cell belongs, and a downlink signal sent by the base station to the UE through the secondary cell can only be sent in a subframe where the DRS is sent. The uplink signal includes at least one of an uplink reference signal, an uplink control signaling, and uplink data. The downlink signal includes at least one of a downlink reference signal, a downlink control signaling, and downlink data.

Specifically, when the secondary cell is in the uplink open state and the downlink open state, if the serving base station of the UE and the base station to which the secondary cell belongs are the same base station, step 1102a is executed; if the serving base station of the UE and the base station to which the secondary cell belongs are different base stations, step 1102b is executed.

Step 1102 a: and the service base station of the UE switches the state of the auxiliary cell into an uplink open state and a downlink closed state.

In step 1102a, when the serving base station of the UE and the base station to which the secondary cell belongs are the same base station, the serving base station of the UE may be the base station to which the primary cell belongs or may not be the base station to which the primary cell belongs. When the serving base station of the UE is the base station to which the master cell belongs, the base station to which the master cell belongs and the base station to which the slave cell belongs are the same base station, and when the serving base station of the UE is not the base station to which the master cell belongs, the base station to which the master cell belongs and the base station to which the slave cell belongs are different base stations.

Step 1102 b: and the service base station of the UE sends a control instruction, wherein the control instruction is used for instructing the base station to which the auxiliary cell belongs to switch the state of the auxiliary cell into an uplink open state and a downlink closed state.

It can be understood that, in step 1102b, the serving base station of the UE may be a base station to which the primary cell belongs, or may be a base station to which a secondary cell other than the secondary cell in the handover state belongs in the serving cell of the UE.

It can be understood that, by performing step 1102a or 1102b, the serving base station may change the state of the secondary cell, so that the state of the secondary cell is an uplink on state and a downlink off state.

Step 1103: and the service base station of the UE sends a downlink deactivation signal to the UE, and the downlink deactivation signal is used for indicating the UE to carry out downlink deactivation of the auxiliary cell. This step 1103 is an optional step, and may be performed after step 1102a, or after step 1102 b.

In a specific implementation, when the base station to which the primary cell belongs is the same as the base station to which the secondary cell belongs, after the state of the secondary cell is the uplink on and downlink off state (step 1102a), the base station to which the primary cell belongs (i.e., the base station to which the secondary cell belongs) may directly send the downlink deactivation signaling of the secondary cell to the UE. When the base station to which the primary cell belongs is different from the base station to which the secondary cell belongs, after the state of the secondary cell is an uplink open and downlink closed state (step 1102b), the base station to which the secondary cell belongs first sends a downlink deactivation signaling of the secondary cell to the base station to which the primary cell belongs through a backhaul link, and then the base station to which the primary cell belongs sends the downlink deactivation signaling of the secondary cell to the UE.

Step 1104: and when the UE works in the uplink activation and downlink activation state of the auxiliary cell, the UE deactivates the downlink of the auxiliary cell according to the downlink deactivation signaling, so that the UE enters the uplink activation and downlink deactivation state of the auxiliary cell.

In other embodiments, the UE may also be respectively provided with an uplink deactivation clock of the secondary cell and a downlink deactivation clock of the secondary cell. When the UE enters an uplink activation and downlink activation state of the auxiliary cell, the UE simultaneously starts an uplink deactivation clock of the auxiliary cell and a downlink deactivation clock of the auxiliary cell, the value of the uplink deactivation clock of the auxiliary cell is a set first initial value when being started, and the value of the downlink deactivation clock of the auxiliary cell is a set second initial value when being started; when the UE receives an uplink scheduling signaling of the auxiliary cell in a subframe for receiving downlink signals, the UE resets the value of an uplink deactivation clock of the auxiliary cell to a first initial value; when the UE does not receive the downlink scheduling signaling of the auxiliary cell in the subframe receiving the downlink signal, the UE subtracts 1 from the value of the downlink deactivation clock of the auxiliary cell; and when the value of the downlink deactivation clock of the auxiliary cell is reduced to 0, the UE performs downlink deactivation of the auxiliary cell, so that the UE enters an uplink activation and downlink deactivation state of the auxiliary cell.

After downlink deactivation of the secondary cell, the UE specifically has the following behaviors:

1) still transmitting the SRS on the secondary cell;

2) still detecting a PDCCH signal comprising an uplink scheduling signaling;

3) transmitting uplink data on the secondary cell;

4) still keeping the uplink deactivation clock of the auxiliary cell;

5) and stopping measuring the downlink channel quality of the secondary cell and sending a detection result of the downlink channel quality of the secondary cell to the base station, wherein the detection result of the downlink channel quality of the secondary cell comprises CQI, PMI, RI and PTI.
